Three experts indicate which machines to choose so that the sports session is as effective as possible. Among the most effective machines, the elliptical bike and the rower come out on top.

“Fat loss (on average between 100 and 200 gr/day) is compensated by muscle gain,” explains biomechanics professor Alain Belli. In recent years scientists have favored moderate interval training (alternating running and sprinting) as a way to burn fat. Or 30 seconds of intense exercise then 30 seconds at a low pace, repeated 5 to 10 times, with 15 minutes of warm-up beforehand, allows for better muscular and cardiovascular intensity and endurance, says sports doctor Jean-Christophe Miniot. The thigh press is a complete machine that will act on the glutes, quadriceps and calves at the same time, says professor Belli, and it is good to pay attention to foot placement during the exercise. The more you develop these, the more your body will need to expend energy and eliminate fat.
